Plumage cues Dan? Roseate Terns are frequently observed offshore at Harkness. Cleaner, whiter overall look and the give the appearance of hitting the water faster than Commons.

I saw 2 terns feeding offshore today at Harkness that I believe were Forster's. Common terns were in the background and these 2 had a completely different flight pattern from those. They flew back and forth banking left and right as they did, sometimes plunge diving from low heights. I could not locate any satisfactory videos online. Any thoughts appreciated.
Thanks,
